What is synonymous with 'affect'?

The term 'affect' primarily refers to the observable expression of emotion or feelings. In psychological and therapeutic contexts, 'affect' is used to describe the emotional response or the mood that a person displays, which can be assessed through facial expressions, tone of voice, and other non-verbal cues. The connection to 'emotion' highlights this aspect because emotions are internal experiences that, when expressed, can be seen as affective states.

While 'feeling' can sometimes overlap with 'affect,' it is often considered more subjective and personal. 'Physical sensation' relates more to tangible bodily experiences rather than emotional states, and 'intuition' pertains to instinctive knowledge or understanding, which does not directly align with emotional expression. Thus, 'emotion' stands out as the most fitting synonym for 'affect' in this context.
